What is a VPN?
VPN stands for the virtual private network, and it gives you online privacy and anonymity. It creates a private network from a public internet connection. As well as it masks your internet protocol or IP address. So your online actions are untraceable, and you become completely anonymous online.
Also, a VPN helps in establishing a secure and encrypted connection between your device and the server. So no one can know what websites you are visiting or what you are doing online.
What a VPN Does?
What a VPN does is that it encrypts your data. As a result, hackers cannot get into your computer or device and figure out what you are doing online.
VPN creates an encrypted tunnel that prevents hackers, and internet service providers from snoopers your internet activities. As a result, they will not know what websites you are visiting, your credit card information, download details, or any other information.
Also, the tunnel cannot get penetrated, and no one will get to see the data transmission, which is happening on your device. VPN makes the whole connection private, and it can make any public network private.
In short, you can say that VPN protects your data. It protects everything from instant messages, emails, downloads, login information, and many more. Even, it also hides your IP address so no one will get to know your real location. Must Check – Gain Competitive Intelligence With Netbase Quid
Why a VPN Is Important?
Now the question is why a VPN is important? Well, no matter where you use your device, you are always under the risk of a data breach.
Unencrypted data is very vulnerable, and hackers can steal it. Hence, going to the internet without any sort of protection is a bad idea. Even when you are using public wireless connections, you must use a VPN.
As hackers can use public wifi connections that you are connected with to hack into your compute. And once they are hacked into your device, they can get all of your private information pretty easily. Hackers can use different ways to spy, steal data, hijack devices, and steal identities when you are using unsecured connections.
But when you are using a VPN, it protects your computer from sniffers and hackers and gives you protection against all types of hacks.
How Does a VPN Work?
To know better about VPN, you should also know the science behind VPN like how it works. Well whenever you connect your computer or any other device to a VPN server, your computer acts as if it is on the same local network as the VPN.
As a result, all network traffic is sent over a secured connection to the VPN. This makes your computer believe that it’s on the same network. So you can securely access local network resources even when you are sitting in some other part of the world.
Also over a VPN connection, you will be able to use the internet as if you were present at the VPN’s location which has some benefits when you are using public wireless connections or trying to access geo-restricted websites.
Moreover, when you browse the internet while staying connected to a VPN, your computer contacts the website through an encrypted connection. The VPN forwards the request for you and returns with the response from the website through a secured connection. Also, the website will see some other location and not your actual location.

What a VPN Does to Protect Your Computer?
Encryption
A VPN helps in creating a secure connection between two devices over the internet and encrypts your information. VPN encrypts your data before sending it to the server. And then again, it decrypts your data once the data reaches its online destination.
Moreover, most of the VPN providers nowadays use the Blowfish algorithm, DES, AES 256-bit encryption. As a result, it becomes harder for the hacker to break the data and steal anything. Apart from these, a 2018 report suggests a new VPN encryption method in which Multi-phase encryption is used for payload encryption, which will only be applied to the data inside the IP packet of the encapsulated tunnel packet. Thus giving more security over the regular VPN encryption methods.
IP masking
Another thing that VPN does is that it masks your IP. An IP address is the home address of yours online. Even, sometimes IP address contains the real address of you. And it’s become easier for anyone to track you down.
However, when you use a VPN, you connect to a VPN server before going online. As a result, all of your online activities are masked by the server’s IP address and not yours. As a result, your real IP address is hidden.
So hackers will not figure out your real location, can’t rack down your network nor they can access your data or mess around with your IoT devices.
In short, VPN is a great way to secure your devices and makes it extremely hard for hackers to crack your privacy. Related – KineMaster for Windows 10 PC
Final Words
So that was the answer to what a VPN does to protect your computer question. VPN is extremely useful and a recommended tool for online privacy. Even, with a VPN, you get to experience a wide range of features too apart from enjoying a high level of privacy.
Also, I would like to recommend you to always use premium VPNs instead of the free ones. Free ones are not reliable, and they mostly sell your data to third parties. As a result, your activities are not anonymous online.
